2.10 Call Rejection (DND)
Do Not Disturb (DND) can be used to avoid phone calls.
To activate DND, press ‘DND’. The icon will be displayed on the LCD screen. When DND is
activated, callers will hear busy tone or a voice mail message if voice mail is available. A DND
forward number may also be set (See Section 3.2.4 or 3.4). If this is set, all calls will forward to
this number. Calls can still be made when in the DND mode.
To deactivate DND, press ‘DND’ again. The icon will disappear.
